Classification of animals. All around the world many different types of animals are present. Many animals are quite similar to each other while others are different from others. So animals can be classified based on their similarities. The whole animal kingdom is divided into two main groups. They are Vertebrates and Invertebrates.
The two major kingdoms are Kingdom Plantae for plants and Kingdom Animalia for animals. This two kingdom classification laid the base for modern classification and was quite a reasonable at that period of time, plants and animals in this system could be very clearly distinguished. Plants were fixed, stationary in the soil, they absorb water for growth and they could prepare their own food.
